Ramesh Raskar‘s team at MIT Media Lab have built a camera capable of capturing light trajectories at a trillion frames per second. Which is relatively fast. Jared Newman at Time’s Techlandpoints out that if it were slowed to a more conventional frame rate of around 30 fps, you would need an entire lifetime to watch just a tenth of a second of this footage.

Moran Cerf is a computational neuroscientist at Caltech. Some of his work is really interesting. Here, though, he describes his life before science—as a hacker and security tester. It’s easily one of the best stories I’ve heard in a while.

A family friend put me on to the great Sixty Symbols (cheers, Cam)—a collection of videos featuring academics at the University of Nottingham. Each one is focused on a symbol with some important meaning in physics: γ links to a five-minute explanation of the Lorenz factor and time dilation; ψ to ten minutes on the wave function. Here’s Laurence Eaves and Mark Fromhold on chaos and the butterfly effect.
